"Okay so I bought this for my JGm700 and at first it was amazing! Hitting a 12 inch target at about 150-woo feet. But slowly I noticed that the bolt was easier to pull back than it was at first. At first is was very hard to pull back, but now it was way easier for one reason. So my .30gram bbs were not going as far or as fast. So not I'm guessing the fps is somewhere between 380-430 with .20grams. Keep in mind I am using .30's so I don't think the bbs are really the problem.

Pros
Good fps

Cons
Hard to bull back

"Great spring with the right equipment with it such as piston & cylinder. I need time to break mine in my JG BAR10. It chronoed around 570.

"Works great. A lot harder to pull the bolt back, but the FPS increase is worth it. I went from 410 FPS with the stock spring, to 510 FPS. Get the sear set and the spring guide to make sure you don't destroy your gun.
